Why, after the portable hard drive is connected to the computer, there
appears a prompt showing that “the high-speed USB device has been
connected to the non-high-speed USB hub”?
Answer: This is because the portable hard drive you are using is of USB 3.0/2.0
specification, while your USB port is 1.1. Basically, the speed for 3.0/2.0 will be
reduced to that for USB1.1, and no other problems will appear. Please try other USB
ports. Only by using the USB 3.0/2.0 port is high-speed transmission available.

drive, the message “Unsafe Removal of Device” will appear. Why?

the taskbar – the “Unplug or Eject Device” icon
→

STORAGE DEVICE”

When a file is copied in the Lenovo Portable Hard Drive, the computer will
display that the copy is over, but when the Lenovo Portable Hard Drive is pulled
out, it will display that the file data is not yet copied successfully. Why?
Answer: The operating system creates a very large chunk of memory for disk
read/write to buffer data. Therefore when the progress bar of the operating system
indicates that the data transmission is over, it does not necessarily mean that the
data has been truly written to the Lenovo Portable Hard Drive. The user should
pay attention to the indicator of the Lenovo Portable Hard Drive: if it flashes, the
Lenovo Portable Hard Drive can not be pulled out; and only after the indicator
stops flashing for a period of time (generally 2 seconds) can the Lenovo Portable
Hard Drive be pulled out.
